QUESTION A:

Find the GCD (or HCF) of numerator and denominator

GCD of 15 and 30 is 15

Divide both the numerator and denominator by the GCD

15 ÷ 15

30 ÷ 15

Reduced fraction:

1/2

Therefore, 15/30 simplified to lowest terms is 1/2.

Thus, option d is your answer

QUESTION B:

Find the GCD (or HCF) of numerator and denominator

GCD of 12 and 3 is 3

Divide both the numerator and denominator by the GCD

12 ÷ 3

3 ÷ 3

Reduced fraction:

4/1

Therefore, 12/3 simplified to lowest terms is 4/1 or 1/4.

Thus option a is your answer

Solve the equation for all real values of x. cosxtanx - 2 cos x=-1

IceJOKER [234]

Solution to equation $cosxtanx - 2 cos^2 x=-1$ for all real values of x is $x=2k\pi + \frac{\pi}{6} , x=2k\pi + \frac{5\pi}{6}$ .

Step-by-step explanation:

Here we have , $cosxtanx - 2 cos^2 x=-1$ . Let's solve :

⇒ $cosxtanx - 2 cos^2 x=-1$

⇒ $cosx(\frac{sinx}{cosx}) - 2 cos^2 x=-1$

⇒ $sinx = 2 cos^2 x-1$

⇒ $sinx = 2 (1-sin^2x)-1$

⇒ $sinx = 1-2sin^2x$

⇒ $2sin^2x+sinx-1=0$

By quadratic formula :

⇒ $sinx = \frac{-b \pm \sqrt{b^2-4ac} }{2a}$

⇒ $sinx = \frac{-1 \pm \sqrt{1^2-4(2)(-1)} }{2(2)}$

⇒ $sinx = \frac{-1 \pm3}{4}$

⇒ $sinx = \frac{1}{2} , sinx =-1$

⇒ $sinx = sin\frac{\pi}{6} , sinx = sin\frac{3\pi}{2}$

⇒ $x=\frac{\pi}{6} , x=\frac{3\pi}{2}$

But at $x=\frac{3\pi}{2}$ we have equation undefined as $cos\frac{3\pi}{2}=0$ . Hence only solution is :

⇒ $x=\frac{\pi}{6}$

Since , $sin(\pi -x)=sinx$

⇒ $x=\pi -\frac{\pi}{6} = \frac{5\pi}{6}$

Now , General Solution is given by :

⇒ $x=2k\pi + \frac{\pi}{6} , x=2k\pi + \frac{5\pi}{6}$

Therefore , Solution to equation $cosxtanx - 2 cos^2 x=-1$ for all real values of x is $x=2k\pi + \frac{\pi}{6} , x=2k\pi + \frac{5\pi}{6}$ .

Jude factored 28x2 as (14x)(2x²).

Yuri [45]

Answer:

Only Jude

Step-by-step explanation:

To show 28 x 2 we show 14 x 2 x 2

The x would be cancelled out in this process so x *x would work to enable a product of 56.

What’s the derivative of sin^2(cos(x^2))

Varvara68 [4.7K]

Answer: f'(x) = - cos^2(sin(x^2))

Step-by-step explanation:

Derivative of:

f(x) = Sin^2(cos(x^2))

f'(x) = cos^2(-sin(x^2)

f'(x) = - cos^2(sin(x^2))
